I have 2 questions that came up in the course of learning to play Zoo (at least, better than playing dorks and turning them sideways, hopefully):

First, I'm 99% sure of the answer to this, but for some reason it keeps coming up as a result of the MWS effect. If a Blood Moon effect is in play and someone plays Price of Progress, what is the net result (supposing, for example, I have 1 Taiga and 1 Plateau in play and my opponent has 2 Tundras and 1 Underground Sea? My interpretation is that Blood Moon checks every time state-based effects are checked without itself changing the supertype of affected cards, so a Price would deal 4 damage to the caster and 6 damage to the caster's opponent in the above scenario.

The second question, I have no idea of. If my opponent chooses to do something EOT, for example cast an instant or spin Sensei's Divining Top and I choose not to respond to the spell/ effect, will I get the opportunity again after it resolves but before the turn changes? For example, I declare I want to end my turn. My opponent chooses to spin top and I decide not to respond. He looks at 3 cards, rearranges them and puts them back. Is there a window of opportunity where I can do something before his turn begins? Or once the top effect resolves, is the turn over and his untap phase begins? As a second part to the question, supposing there is an opportunity for me to do something, does this opportunity happen at the end of every phase? Like, if it were my Precombat Main Phase, I declare I want to move to my Beginning of Combat phase. He tops end of phase and finishes. Now, can I do something else (having previously declared I want to move to my Beginning of Combat phase), or does the phase change?
